METHOD or MAKING Application fiie'dfxurie 22,

The object of .thisinveiitioii is to disclose pressed through a die at one end of the brick-machine and is received by. a traveling belt or conveyorand carried to the cuttingwires wlieretlie columnis sliced into the form of bricks. I i

By my invention the desired exterior surface is produced upon the clay intermediate of the die and the cutting wires This ex terior appearance or surfacing is secured by means as herein set forth but other means for performing the steps of my processmay suggest themselves to those skilled. in the art, as for instance, spikes or spades equally spaced in'a frame transverseto the longitudinal axis of the column. of clay, might be substituted for the rotating brushes to out the parallel striae on the face andsides ofthe clay column, or paddles be substitutedfor teferring to the accompanying drawings: 1

The operative parts of the machine are carried-by a base-franie 9. The ordinary die 6 delivers a column of clay or shale over an idler-roll supporting this column to a conveyor belt 10. A horizontal revolving brush 12 supported in frame 11 is rotated by pulley and shaft 15. This brush 12 cuts upon the surface of the column of clay fine parallel striae 16 longitudinally of the col-' umn of clay; likewise similar vertical brushes 13 out similar parallel striae 16 lon gitudinally on the sides of the column of clay these vertical brushes being driven by the pressing roller, or other means for re-e Fig. 2 is a horizontal side elevation of the ORNAMENTAL: BRICK. 192%.

bevel-gears M from the shaft of the brush 12. A roller 19 is held against the column of clay by spring .17, giving said roller sufli eient pressure to operate the roller and cams attached thereto. Q

Supported in framc22 is a harrow-toothed reciprocating sci-atelier 20 which is reciproeated transversely to the travel of the column of clay by rollers operating against the cam faces of Wheels 18 on the shaft of the roller 19. This scratcher forms substantially parallel grooves approximately a quarter of an inch wide and a quarter of an inch deep; running in wave-like lines longitudinally of the surfaces of the column of clay, asshown at21. A second stationary scratcher 23 having harroW-like teeth may be interposed to cut additional heavy groovesbetween the wavy grooves produced bythe scratcher 20 but this is optional and may be dispensed with. roller 24held by the pressure of spring 25 against the column of clay. serves to roll upon and re-attachto tliecolumn of clay, the laminae of clay plowed out by the scratchers. The sidescratcliers 31and 34 produce on the side of the column of clay the same Wavy and straight furrows as are produced by 20 and 24, and inthis connection rollers 33 and 35 supported in the frame rotate to re-attach the laminaeof clay detached by the scratch ers tothe' sides of the column of clay, as

in the case of rollers 19 and 24. On a frame 30 a lever 28 is pivoted which is actuated by a pitman 27 attached to a crank 26 on the shaftof roller 24 and to the end of lever 28 the scratcher 31 is attached and is recip- Fig. 3 is a transverse cross sectlonon the rocated by said lever. The rollers 33 and 35 are supported by frame 32 and are held in tension by spring 36. 37 and 38 indicate the finished horizontal and vertical surfaces of the column of shale or clay after they have been treated by the brushes, the scratchersand the rollers. At the ends of frame 9,

clay by means of a tension spring 41 and these further serve toattach the laminae of clay to the surface of the column of clay.

42 is the ordinary brick cutter assembly for tree-bark, but in all such methods to produce Iarms 39 support rollers 40 which press against the vertical sides of the column of Ill such an efi'e'ct in brick, carehas been taken to prevent the flakes or laminae which result from plowing out the grooves, from becoming re-attachecl to the surface of the claycolumn and so appearing upon the surface of the burned brick. One of stheiflbjects Of my invention is to utilize these flakes and laminae and so give to the surface of the brick the appearance of excrcscences, gnarls, or knots; instead of wasting this r'nateridl.

I claim asmy invention:

The art andproccss of surfacing a plastic column of clay before cutting the smile into bricks, as the column of clay is pressed through a die at one end of a brick machine "and carried by a traveling-belt or conveyor to the cutting Wires at the other end of such brick machine, by cutting on the upperfa'ce and one side of said column of cldy, parallel longitudinal striae, then plowing into the upper face and on the same vertical side thereof, longitudinal wavy furrows-of a cross section severaltimes wider and deeper than said strise and in such step throwing out upon thesnrfaceof the column of plastic clay the material plowed out of such furrows in lumps,- sli'uvings or lamina; then pressing said lumps, shavings or luminae'
